Geared motor is an independent closed transmission device located between the prime mover and the working machine. It is used to reduce the speed and increase the torque accordingly. Geared motors are mainly divided into two categories: geared motors and worm geared motors. The gear reduction motors are mainly divided into cylindrical gear reduction motors, bevel gear reduction motors, and cone- | cylindrical gear reduction motors.

Geared gear motors are characterized by high efficiency and reliability, long working life, easy maintenance and wide application. The number of stages of the gear reduction motor can be divided into single-stage, two-stage and three-stage gear reduction motors. The installation arrangements of the gear reduction motors mainly include expansion, coaxial and shunt. In the two-stage cylindrical gear reduction motor, the gear is asymmetric with respect to the support position. When the shaft is bent and twisted, the load is unevenly distributed in the tooth width. Therefore, the shaft should be designed with greater rigidity and the gear should be away from the input Or output.

The characteristics of the split type of the two-stage cylindrical gear reducer motor: the position of the extended shaft of the split reducer motor can be extended from any side, which is convenient for the overall configuration of the machine. In order to offset the axial force, one of the shafts should be allowed to move slightly in the axial direction, so as not to jam the gear.

The characteristics of coaxial geared motor: compact radial size, but larger axial size. Due to the large intermediate shaft, the shaft has greater disturbance under load, so the load concentration along the tooth width is more serious. At the same time, since the centers of the two-stage gears must be the same, the bearing capacity of the tell-stage gears is difficult to make full use of, and the lubrication of the bearings located in the middle of the reduction is also difficult. The input and output ends of the geared motor are located at both ends of the same axis, which limits the overall configuration of the transmission.
